ABSTRACT:
A photocurable composition comprises a radical-polymerizable unsaturated group including a mixed material which consists of polyethylene glycol di(meth)acrylate and dipentaerythritol hexa(meth)acrylate as a base material, an iron arene compound as a photopolymerization initiator, and an aniline system compound which is N,N-Dimethylaniline as a photochemical sensitizer for having a photocuring sensitivity to light having a wavelength in the range from the ultraviolet region to the infrared region. A photocurable composition comprises a radical-polymerizable unsaturated group including a mixed material which consists of polyethylene glycol di(meth)acrylate and dipentaerythritol hexa(meth)acrylate, as a base material, an iron arene compound as a photopolymerization initiator, and a cyanine system compound which is 2- 2- 2-chloro-3- (1,3-dihydro-1,3,3-trimethyl-2H-indole-2-ylidene)ethylid ene!-1-cyclohexane-1-yl!ethenyl!-1,3,3-trimethyl-3H-indolium salt as a spectral sensitizer for having a sensitivity to light having a wavelength ranging from the visible region to a near infrared region. A photocomposition comprising the base material, the photopolymerization initiator and both the photochemical and spectral sensitizers may also be used to obtain the photocuring characteristics.
